STEPHEN V. APPLEBY, OF NEW YORK, N. Y.

MACHINE FOR DRYING WET GRAIN, 8m.

Specification of Letters Patent No. 14,588, dated April 8, 1856.

To all whom t may concern.'

Be it kno-wn that I, STEPHEN V. APPLEBY, of New York, in thevcounty andState of New York, have invented a new and useful Machine for Drying VetGrain or other Similar Substances Damaged by Vater; and I do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawings and to the letters ofreference marked thereon.

The nature of my. invention consists in the arrangement of a series ofrevolving` cylinders, placed one below the other within a heated flue,with the ends of said cylinders projecting through into flues, intowhich cold air is forced. l/Vet grain or other similar, by waterdamaged, substances, are thrown into the top cylinder, pass through thisheated cylinder, and fall then into the neXt cylinder lying underneaththe former, being met in its fall from one cylinder to the other by acurrent of cold air. By this arrangement the wet grain is kept"constantly in motion and is acted upon alternately by heat and coldair.

A, A', &c., are cylinders, made tapering so that grain put in at thesmall end will easily fall through the same. The cylinders are laid oneabove the other into a flue X with their ends, which are open,projecting a short distance through the side walls WV, W, forming theflue X and are supported on the outer walls (W, W,) by bearings (a, a&c.). Y

(n, m, n, m, &c.) are platesfastened to the side of the walls (W WV) andcover the ends of the cylinders partly up, leaving an opening at thebottom for the grain to fall into and out of the cylinders. These platesare for the purpose of preventing in some measure the free passage ofthe cold air through the heated cylinders. Near the top in the plates(m, m, &c.) small holes are made to allow the vapors to escape out ofthe cyliders.

(Z, Z, Z &c.) are iues through which the grain falls from one cylinderinto the other, and into which the cold air is forced to meet the grainin its fall.

p, &c.) are openings near the top of the ues (Z, Z", Z", &c.) to allowthe air and vapor to escape. These openings are covered up with wiregauze to prevent any grain being blown out.

(g, g, 9, Q', g. y. &C) are gratings .fXed into the flues (Z Z &c.) toincrease the distance the grain has to fall between one cyl,- inder andthe other, and there-fore increase the time for the cold air to act uponthe same.

(h, t, L, &c.) are gratings to lead the grain into the mouth of thecylinder.

(P,` P, &c.) are pipes conducting cold air into the lines (Z Z &c.).

(f, f, f, Sac.) are pulleys attached to the end of the shafts of thecylinders (A, A &c.) t0 turn the same around. Instead of making thecylinders in the shape of cones as here represented the same may be madecylindrical and placed in that case on an incline s0 that the grain willeasy fall through.

The operation is as follows. The cylinders being set in mot-ion, the wetgrain is thrown into the flue (Z) and passes, guided by the grate (it)into the cylinder (A) where by means of heat produced in the flue (X)some part of its moisture will be absorbed, and the vapor escape out ofthe cylinder through the hole in the plate (m). The grain then falls outofthe cylinder (A) into the flue (Z) upon the gratings (g) and (h),through which latter it is guided into the cylinder (A) a blast of coldair is thrown into theliue Z by the pipe (P) meeting the heated grain asit falls from one cylinder into the other, and down the differentgratings (g), cooling thereby the same and carrying off the vapors,which escape together with the air through the opening (p) .into theopen air. From the cylinder (A), where more of its moisture is againabsorbed, the grain passes or falls through the liue (Z) into thecylinder (A) being met on its passage through the flue (Z) by a freshstream of cold air, and so on passing from one cylinder into the other,being subjected alternately to heat and cold air until the same isperfectly dried.

What I claim as my invention and desire to secure by Letters Patent isThe application of revolving cylinders situated in a heated flue, withtheir ends Drojectng into ues, into which cold air heat While in thecylinder, and to the action .s forced, and so arranged that grain, or ofcold air While falling from one cylinder )ther similar substances putinto the top into the other for the purpose specified.

zylinder will slide through the same and STEPHEN V. APPLEBY. :hen fallinto the next cylinder and so on Witnesses: from one into the other,being in its pas- SAMUEL COTTON,

age alternately subjected to the action of HENRY E. BOEDER.
